Done the same with moles,,and fen 6 trapping squirrels,,,but both species are easily trapped,,,,
Ive always wondered though,,,these speed dips,,surly they have some kind of smell,,even if us humans can't smell it,,,so it begs the question,,,would the trap be better left with a bit of oil on it...
Look at socks pics,,,,mixed with petrol,,,why not just leave it,,,
